Question

Quizplus · Accepted Answer

Abnormal genes can be detected most accurately by examining DNA, as mutations or variations in the genetic sequence can be directly identified through DNA sequencing or other genetic analysis techniques. Enzymes, substrates, products, and mRNA can give indirect evidence of abnormalities in gene function, but DNA analysis is the most direct and reliable method of detecting abnormalities at the genetic level.
